BRIDGE-WARNING.

, Specification of Letters Patent. P t nt d Nov. 30, 1920.

Application filed May 29, 1920. Serial No. 385,221. 7

To all whom it may concern. 7 I

Be it known that I, VVILLIAM S'rn'iMPLE, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State I of New Jersey, have invented a new and Improved Bridge-WVarning, of which the following is a full, clear, and exact descriptionf This invention relates to bridge warhings,

and has reference more particularly to bridge warnings consisting-of a plurality of rigid suspended members positioned above a railroad track.

As commonly practised, a number of wires or ropes are suspended from a cross arm so as to hang over a railroadtrack so that a; man riding on top of a railroad car willbe struck in the face by these ropes or ticklers which will indicate to the man on the car that he is approaching a bridge which he.

must avoid b stooping in order to pass thereunder.

these ropes become wet in the winter time, and freeze up so that the man on the car is dealt a heavy blow by the rope. The wires or suspended ropes are also bent out of shape and thrown up under the cross arm by the railroad man or by the exhaust of the engine, so that a crew of men must be kept at work keeping these bridge warnings in condition.

An object of this invention, therefore, is to provide bridge warning members which are rigid so that they may not be bent or twisted out of shape, and which will not absorb water and freeze in the winter time.

'Reference is to be had to the acompanying drawings forming a part of this specification, in which it is understood that the drawings illustrate only one form of the invention with certain modifications, and in which V Figure l is an elevation of my improved bridge warning.

Fig. 2 is a fragmentary'detail view of the bridge'warning on a large scale.

Fig. 3 is a detail View on a largescale of one of the suspended members with parts broken away to disclose the construction.

Fig. 1 is a fragmentary elevation on a large scale of one of the suspended members.

Fig. 5 is an elevation of a modified form of my bridge warning adapted to be used on several tracks.

t frequently happens that Fig. 6 is a sectional view through the bridge warning. on theline 6-6 of Fig. 5. Referring to the accompanying drawing by numerals, 10 indicates an upright stand ard or support. A cross arm 12 is secured to the standard 10 by bolts 13 secured to a collar 14, said collar encircling the standard 10. An oblique brace 15 is secured at its upper end to the .cross arm 12 by a collar 16 and at its lower end to the standard 10 by a collar 17. The cable 11 extends from the bottom of the standard 10, towhich it is fastened in any suitable manner, over the curved top of the standard 10, out to the end of the cross arm 12, whereby ,the cross arm 12 is stayed by the cable 11 in conjunc- .tion withthe brace 15 to elfectivelycarry the weight of the bridge warning.

A plurality of eye bolts 18 are secured at intervals to the cross arm 12, and a rod 19 passes throughsaid eyebolts and is secured in place by collars 20. tickler heads 21 are suspended at intervals on-the rod 19, and are spaced apart by collars '22. The lower ends of the heads 21 are provided with a recess 23 which is adapted to receive a slat or tickler 24, said tickler being preferably constructed rectangular in cross section, and being made of light-weight wood which cannot be bent and will not absorb moisture and freeze in the winter time. A pin 24L passes through the lower end of the head 21 and the upper end of the tickler 24 so as to hold said tickler in position in the recess 23.

' When the bridge warnings are placed over a number of tracks, a cable 25'is stretched between poles 26 so as to be positioned transversely of said tracks, and said cable 25 is further supported by a bracing cable 27 connected to the cable 25 by links 28. A plurality of clamping members are secured to the cable 25 and to the rods 19,, and these clamping members consist of a pair of metal strips 29, registering arcuate sections 30.

at each end which cooperate to embrace the cable 25 and rod 19., and said strips 29 are heldtogether at their extreme ends by bolts 31.

I would state in conclusion that while the so I A plurality of V can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, I

"5 claim as new and desire to secure by Letters Patent:

' In abridge Warning, a rod, means fer sup- 3 porting said rod above a railroad track a plurality of spaced collars on said rod and a plurality of rigid, suspended members 10 pivotally mounted to said rod and spaced apart by said spacing Collars.
